Add new record for boolean field not editable

Gven this table, I click the plus symbol to add a new row.

The other fields are editable as expected (dates, string)...the boolean field doesn't seem to be something I can change until it has been saved.

-- auto-generated definition
create table contact_emails
(
  id           serial       not null
    constraint contact_emails_pkey
    primary key,
  email        varchar(255) not null
    constraint contact_emails_email_unique
    unique,
  unsubscribed boolean,
  created_at   timestamp(0),
  updated_at   timestamp(0)
);

Also if I define the unsubscribed field default as "false", I only see the word "default" when adding a new row and can't set this to true/false at the time of entry.

This doesn't seem right and I would expect the same behaviour when editing a boolean field (cycling between false, null and true)
